Pierson, who describes herself as a “senior adviser” for Trump’s 2020 campaign and who worked on his 2016 campaign, tweeted that McCain “Still Refuses to Answer Questions About His Role” concerning the dossier, which was compiled by the former British spy and included unverified accusations. Trump supporters insist the dossier is the only reason an investigation was launched into Trump’s connections with Russia.

Pierson’s tweet included a link to one of her 2017 blog posts and its headline.

Since everyone is just now realizing his staffers role in the #RussiaHoax We have been asking questions! John McCain Still Refuses to Answer Questions About His Role in the Dossier https://t.co/acsVdH1GTq

Pierson in turn blasted comments by the “looney left” and tweeted, “You guys are so dumb!” She insisted that her tweet refers to McCain “staffers” — and not the late senator.

She was apparently attempting to make a point about a judge’s ruling Wednesday striking down a defamation suit against BuzzFeed, which printed the dossier. According to the judge’s ruling, BuzzFeed obtained copies of information in the dossier from David Kramer, who was a director at the McCain Institute for International Leadership.

But Pierson’s actual message made it sound as if she were attempting to communicate with the dead.
